Tire tread



FIG. 1 is a perspective view of a tire tread showing my new design, it being understood that the tread pattern is repeated throughout the outer circumference and the shoulder of the tire tread, the opposite side being the same as that illustrated; and,

FIG. 2 is an enlarged fragmentary front elevation view of a portion of the tire tread of FIG. 1, showing my new design.

The broken line showing of a tire inner bead and sidewall is for illustrative purposes only and forms no part of the claimed design. 

The ornamental design for a tire tread, as shown and described.
